November 1, 2011 — IDC Energy Insights published an IDC MarketScape report to help residential photovoltaics (PV) installers evaluate inverter technologies and vendors.
The analysts found that standard string inverters are becoming a commodity, with market share determined by price. Micro-inverters and other innovative products are gaining traction in shaded installations or installations with panels at multiple orientations.
IDC MarketScape: North American Residential Solar Inverter Market, 2011 compares inverters based on installer feedback and other parameters. Technologies compared in the report include string inverters, micro-inverters, and string inverter/DC optimizer solutions. Vendors evaluated include Enphase Energy, Fronius, Schneider Electric (Xantrex), SMA, SolarEdge, and Solectria Renewables. IDC Energy Insights shares recommendations on different inverter vendor selection approaches, based on installer input.

Photovoltaic installations will grow in the US at around 24% over the next 4 years, said Jay Holman, research manager at IDC Energy Insights. Holman notes that inverter technology is “a key differentiator” for installations in this young and technologically evolving industry.
Methodology: IDC analysts tailor the range of standard characteristics by which vendors are measured through structured discussions, surveys, and interviews with market leaders, participants and end users. Market weightings are based on user interviews, buyer surveys and the input of a review board of IDC experts in each market. IDC analysts base individual vendor scores, and ultimately vendor positions within the IDC MarketScape, on detailed surveys and interviews with the vendors, publicly available information and end-user experiences in an effort to provide an accurate and consistent assessment of each vendor’s characteristics, behavior and capability.
